Question

If the initial conditions are inherently zero, what does it physically mean?

(a) The system is at rest but stores energy

(b) The system is working but does not store energy

(c) The system is at rests or no energy is stored in any of its parts

(d) The system is working with zero reference input

I had been asked this question by my school principal while I was bunking the class.

Asked question is from State Models for Linear Continuous-Time Systems topic in chapter State Variable Analysis and Design of Control Systems

Answer 1

Right answer is (c) The system is at rests or no energy is stored in any of its parts

For explanation I would say: A system with zero initial condition is said to be at rest since there is no stored energy.
